PURPOSE To describe a predictive middle range theory (MRT) that provides a process for validation and incorporation of nursing diagnoses in clinical practice. DATA SOURCES Literature review. DATA SYNTHESIS The MRT includes definitions, a pictorial scheme, propositions, causal relationships, and translation to nursing practice. CONCLUSIONS The MRT can be a useful alternative for education, research, and translation of this knowledge into practice. IMPLICATIONS FOR NURSING PRACTICE This MRT can assist clinicians in understanding clinical reasoning, based on temporal logic and spectral interaction among elements of nursing classifications. In turn, this understanding will improve the use and accuracy of nursing diagnosis, which is a critical component of the nursing process that forms a basis for nursing practice standards worldwide.
